For instance, one of my professors went to Princeton (for his undergrad math degree) for free, because his parents are tenured faculty at Princeton. Is such a benefit available to tenured faculty at most U.S. universities? This is assuming that a tenured professor's children are qualified to be admitted to the school.
Besides having academic freedom, what are some other, lesser-known, considerable perks of being in academia as a tenured professor as opposed to being tenure track?
(Main motivation for the question is to follow up on a previous question in which the OP asked about the stresses of academic life, specifically, in mathematics research.)
My father is a retired college professor, and these were some of his "perks."
1) Tuition reimbursement for all his children, up to that of the university[s own fees. In the case of the Princeton professor, that meant his children's tuition at Princeton was paid for.
2) Chances of earning additional money, under the auspices of the University, for government or other consulting projects.
3) A very generous retirement package, similar to that of the military or government employees. The "salaries" aren't so great, but the retirement benefits are.
Note that this refers to what has been in the past,for people who are now closer to retirement than to receiving tenure, and may or may not be true going forward. But the question was cast as 'up to now."
